Subject: [ruby-core:48965] [ruby-trunk - Feature #7288][Open] Documentation missing: FileUtils.chmod "+X", "directory"


Issue #7288 has been reported by joerg.herzinger (J��rg Herzinger).

----------------------------------------
Feature #7288: Documentation missing: FileUtils.chmod "+X", "directory"
https://bugs.ruby-lang.org/issues/7288

Author: joerg.herzinger (J��rg Herzinger)
Status: Open
Priority: Normal

Target version: 


Documentation for chmods "X" (uppercase) feature is missing. This sets the execute bit on directories but not on files. Tested on my Ubuntu machine it works although not documented.
Reproducable like this:

[irb]
require 'fileutils'
FileUtils.cd "/tmp";FileUtils.touch "testfile";FileUtils.mkdir "testdir"

FileUtils.chmod "-x", "testfile"; FileUtils.chmod "-x", "testdir"
File.executable? "testdir" => false
File.executable? "testfile" => false

FileUtils.chmod "+X", "testfile"; FileUtils.chmod "+X", "testdir"
File.executable? "testdir" => true
File.executable? "testfile" => false
[/irb]

From chmods man page:
... execute (or search for directories) (x), execute/search only  if  the file is a directory or already has execute permission for some user (X) ...
